Improper Maintenance Causes MIA People Mover Incident

MIAMI (CBSMiami) – Human error was to blame for last month's derailment of a people mover train at Miami International Airport.

Last month the train went off the tracks as it was headed toward the adjacent rental car center on LeJeune Road.   When the MIA Mover entered the crossover, one of its wheels went off the track, the rear car derailed and tipped to the right, according to CBS4 news partner The Miami Herald.  Among the 12 passengers only two suffered minor injuries during the accident,

According to a new report investigators with Mitsubishi and Crystal Movers determined that the guide-wheel assembly bolts had not been properly "torqued or worked loose".

The train had undergone routine maintenance review the day before and was tested throughout the night, just hours before it derailed.

Commissioner Dennis C. Moss was sent a report Tuesday. He stated that the Operations and Maintenance department will implement stricter policies for maintenance workers.

As a result workers will take part in a refresher training that is meant to prevent any future mechanical failures.
